At the start of the week the MTA announced there would be $50 fines for transit riders refusing to wear a mask. By Friday afternoon, the agency announced that MTA police and Bridge and Tunnel officers had issued zero tickets.

Instead, the agency said there had been 1,700 “positive encounters across the subway system with riders either not wearing masks or not wearing masks properly covering mouth and nose. They have not had to issue summonses to achieve the desired result, [which is] enhanced mask usage that respects fellow New Yorkers and promotes health and safety,” a spokesperson wrote in a statement.

The MTA shared data that noted from Monday to Thursday there were 857 incidents in which officers verbally reminded riders to wear their masks properly. Additionally, 167 masks were handed out.

The NYPD, which had stopped issuing fines after a directive in May, began to help the cash-strapped agency with enforcement of its new mask policy this week. The goal is to ensure riders are less exposed to contracting the coronavirus as commuters begin their return to public transportation as the city begins loosening restrictions and New Yorkers head back to work. The MTA continues to clean up subways, continuing its policy to shut down the entire system from 1 to 5 a.m. to disinfect subway cars using electrostatic technology.

“We’re working with our partners in the MTA, what we want is compliance,” NYPD Commissioner Dermot Shea said on NY1 Monday. “We’re not looking to give summonses and further hurt people that are already hurting in New York City, but we want compliance.”

At the start of the week the MTA noted that across the system about 90% of riders usually wear a mask, but it’s still looking to get universal mask compliance. Riders have had no qualms in reporting mask-less riders to the MTA on Twitter, where they're often directed to provide comments on its customer feedback website.

Mask-wearing is extremely important to wear in an underground subway, particularly in long commutes, said Dr. Scott Weisenberg, an Infectious Disease specialist at NYU Langone, in an interview with Gothamist back in May.

"If you're on a subway that's going from the Bronx to Brooklyn, and you're going to be on that for an hour, that's a higher risk than, say, if I'm going two stops," said Weisenberg.

The NYPD hasn’t responded to requests for information about how many fines its officers issued this week.

One day after the MTA directed the city's cops to crack down on maskless transit riders, a teenager confronted a pair of NYPD officers for not wearing masks inside a Brooklyn subway station. They are caught on video calling him a "male version of Karen" in response.
